SRI (Solar Reflective Index) measures a roof’s ability to reject solar heat (reflectance) and the ability to emit heat out (emittance). Cool roofs reflect and emit the sun heat instead of absorbing it. A cool roof is one that reflects the sun’s heat and emits absorbed radiation back into the atmosphere.
